German Chancellor Angela Merkel says the actions of protesters who shouted abuse at a bus full of migrants earlier this month were "repulsive" and "unjustifiable."

Video of about 100 people trying to block migrants from entering a shelter in the eastern village of Clausnitz on Feb. 18 prompted concern about growing radicalization in Germany due to the influx of migrants.

Merkel told public television ARD late Sunday that Germans who question her actions in the refugee crisis "aren't convinced yet but I think that I can convince them if the issue is resolved."

She says more needs to be done to solve the problems causing people to flee to Europe, but also that those coming to Germany have to abide by its laws.
